...assuring

It is my opinion that quality ensuring would be a better expression, but in the literature normally assuring is used.

...DPV

Diabetes Softwaresystem zur prospektiven Verlaufsdokumentation - German name of a diabetes information system.

.
.
.
.
.
.

.
.
.
.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...triangle

Note that test cases like (1, 2, 3) or (2, 4, 8) does not warrant a ``yes'' answer, because there is no triangle with those sides.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...triangle

Caveat: (2, 2, 4) is not counted here!

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...third

It is definitely a bug if the program says (1, 2, 3) is a scalene triangle!

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...validation

Did we built the right product?

.
.
.
.
.

.
.
.
.
.
.
.
.
.
.

...verification

Did we built the product correctly?

.

...expenditures

In general the costs to fix bugs grow exponentially in the course of time.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...prepared

It has been determined that the efficiency decreases significantly if the individual team members have less than eight hours time for this.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...author

Some demand that this should not be done by the author. Here it is the authors job, to have a better distinction from the walk-through.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...meeting

How high are the chances of finding a bug if everybody is sleeping?

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...instructions

Certainly do not all programming languages have loops or if statements, but the examples given here can still be adapted to most languages and they are only examples given for clarity reasons.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...once

This also detects parts which cannot be reached. This suggestion is lots too weak, see different code coverage suggestions in [Gilb94].

.
.
.
.

...example

If you are totally unfamiliar with perl consider reading the crash-course  in chapter  on page  now.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...left

It is sometimes distinguished between nondeterministic and deterministic loops, but that is going too far for this exposition.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...loops

Boris Beizer calls them horrible loops .

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...integers

Some programming languages do not force this, but it is always a possible source for a bug.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...functionality

This is the origion of its alternative name functional testing.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...chosen

Those five representatives overlap and sometimes one is even treated as a subtest of another. Nevertheless, they will be treated independently.

...NAME=383> 

Caveat: Do not get confound with functional testing!

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...tested

[Schweiggert94] has a nice example in which the possible inputs for the example in chapter  on page  are devided into eight equivalence classes.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...Alternatively

Better would be ``in addition'', but the now following test is nearly covered by the sum of domain testing and the equivalence class tests.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...NAME=405> 

Caveat: In this context ``system'' does not mean the whole hardware or something of this kind!

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...important

Some authors even suggested tests like turning off the system's power supply and restarting it, but since those tests are not reproducible they will be ignored here.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...time

This is also known as volume testing.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...alone

This means without the developers and without a testing crew.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...know

This certainly depends on the application.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...system

A collection of libaries or other programs of this kind do not have a good help system, but none of the testing methods is good for all kinds of applications.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...system

Most even dislike producing it.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...tested

Is it easy to change or maintain the program?

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

Those known diabetics have usually type I which is not that common - read the next two sections about this.

...NAME=1279> 

[Welsh95] states about  perl : ``Perl is worth the price of admission to Linux alone'', and this book has only a couple of pages about  perl .

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...systems

Perl was designed for UNIX  at first, but now there are versions for basically every operating system.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...tools

Nevertheless, most of them have been re-implemented in  perl .

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...each

This example is a little bit more complicated than the typical Hello World program, but this is meant to be a crash course, and it shows a lot of perl's nice features.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...false

In  perl a condition is false if it is equal to zero or undefined.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...$_

All scalar values in  perl start with a $ - more about data structures in chapter  on page .

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

.
.

...statement

The condition of an if statement in  perl has a similar syntax as in C .

.
.
.
.

...$3

Anything enclosed in parenthesis in a regular expression is saved for later use in one of the variables $1, ..., $9, $10, $11, ...

In other programming languages like   TCL, Hashes are called associative arrays.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...turn

The variable is implicitly local to the loop and regains its former value upon exiting the loop.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

Like in C  the quick sort algorithm has been implemented.

.
.
.
.
.
.
.

.
.
.
.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...Arrays

Since (()()()) is equivalent to (), because sub-lists are not possible and flattened at once, array is a better word than list.

.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.
.

...versa

For instance %logins = ("melzer" => 11, "plonka" => 5); where => is an equivalent for ,.

...list @_

Caveat: Never try to pass two lists to a function, because you will not know where to split them!
